Answer:

The answer is to insulate Earth's surface temperature.

Explanation:

Clouds inhibit the outflow of terrestrial radiation. This acts to insulate Earth's surface temperature, keeping it warmer at night and cooler in the day.

Define the Element of Art, value. If you were using a pencil, how would you create a darker value?

ankoles [38]

Elements of art are stylistic features that are included within an art piece to help the artist communicate. The seven most common elements include line, shape, texture, form, space, colour and value, with the additions of mark making, and materiality.

You would create a darker value if you shaded it, shading it makes it darker.

An electron is released a short distance above earth's surface. a second electron directly below it exerts an electrostatic forc

slamgirl [31]

The mass of an electron is 9.109 x 10⁻³¹ kg

The weight of the electron is (mass) x (g) = 8.926 x 10⁻³⁰ Newton

The charge on an electron is -1.602 x 10⁻¹⁹ Coulomb

The repelling force between the two electrons is (K · q₁ · q₂ / r²) =

(8.98755 x 10⁹ N-m²/C²) x (1.602 x 10⁻¹⁹ C)² / D²

In order for the bottom one to just exactly hold the top one up at a distance 'D', the repelling force has to be exactly equal to the weight of the upper electron.

8.926 x 10⁻³⁰ N = (8.98755 x 10⁹ N-m²/C²)·(1.602 x 10⁻¹⁹ C)² / D²

We have to solve THAT ugly mess for ' D '.

Clean up the units first:

Cancel the C² on the right side, then divide each side by Newton:

8.926 x 10⁻³⁰ = (8.98755 x 10⁹ m²) x (1.602 x 10⁻¹⁹)² / D²

Now, let's multiply both sides by (D² x 10²⁹) :

D² x 8.926 x 10⁻¹ = (8.98755 m²) x (1.602)²

Divide each side by (0.8926):

D² = (8.98755 x 1.602²) / (0.8926) meter²

D² = 25.84 m²

Take the square root of each side:

D = 5.08 meters

What is the impulse of a 2 kg object that starts at 10 m/s and comes to a stop over 0.4 seconds?

gizmo_the_mogwai [7]

Answer: Impulse = 20 Ns

Explanation:

Impulse is the product of force and time

Also impulse = momentum

Where momentum is the product of mass and velocity.

Given that

M = 2kg

V = 10 m/s

Impulse = MV = 2 × 10 = 20 Ns

LINK THE WORDS TO THE UNDERLINE. The 4 most common _____________ are solids, liquids, gases and plasmas. The _______________ are

Savatey [412]

The 4 most common States of matter are solids, liquids, gases and plasmas. The States of matter are also called the phases of matter.

2. For a given pure substance, the amount of thermal energy is what separates the different states of matter. The solid state has the least thermal energy. The liquid state has more thermal energy than the solid state. The gaseous state has more thermal energy than the liquid state. And the plasma state has the highest thermal energy of the 4 states of matter.

3. Changing from one state of matter to another is called a phase change. Solids can phase change to liquids or gasses. Liquids can phase change to solids or gasses. Gasses can phase change to liquids or solids.

4. Frost forms from water vapor depositing as ice crystal without first becoming liquid water. This is called Deposition. Deposition is also used in industry to put a thin layer of aluminum on mylar for helium balloons and for potato chip bags.

5. Put wet laundry outside on a clothes line in freezing weather and it will dry. The process is called Sublimation and a solid phase changes to a gas without first melting into a liquid. Dry ice (frozen CO2) undergoes Sublimation and becomes CO2 gas. It skips the liquid state and because we see something that looks like normal ice disappear without making a puddle, we call it dry ice.

6. Vaporization is when a liquid becomes a gas. It can happen slowly at cool temperatures and this is called evaporation. Or it can happen faster at the boiling temperature of the liquid and this is called boiling.

7. In the summer time, I love a glass filled with ice water. But water vapor in the air undergoes Condensation and becomes liquid water on the outside of the glass. Fog and clouds are also formed by Condensation of atmospheric water (water vapor) condensing into liquid water drops.

8. Thermic refers to thermal energy, usually perceived as heat or temperature. Endo refers to “inside.” Endothermic means heat is moving INTO a process and is stored in the products of that process. Heating up liquid water is Endothermic because heat is being put into the process of raising the water temperature and is stored in the kinetic motion of the water molecules. Melting ice into liquid water is Endothermic because heat is being used to break most of the attractive bonds between water molecules so that the molecules are still close to each other, but can slide around each other.

9. Thermic refers to thermal energy, usually perceived as heat or temperature. Exo refers to “outside” like exiting a room to the outside. Exothermic means heat moving out of a process. The heat energy comes from energy stored as kinetic motion of the molecules and broken bonds of attraction. When liquid water cools down, heat comes out of the water and goes to the environment around the water. This is Exothermic. Liquid water undergoing the phase change to become solid water (ice) is Exothermic. The thermal energy absorbed to “melt” the ice is released as the ice freezes.

10. The Kinetic Theory of Matter theorizes that all matter is made of tiny particles (atoms and molecules) that are in constant motion. The amount of motion is an indication of the temperature. At absolute zero, all kinetic motion stops.
